Description

L'invention concerne une machine à laver le linge comportant une cuve destinée à contenir l'eau de lavage ou de rinçage, dont le fond présente une cavité à ouverture sensiblement horizontale de laquelle part une canalisation de vidange conduisant à une pompe de vidange. Une telle machine est par exemple montrée dans le brevet US 3 084 530. La cavité située au point le plus bas de la cuve fait office de puisard permettant un fonctionnement régulier de la pompe, sans désamorçage, jusqu'à vidange effective de la cuve.The invention relates to a washing machine comprising a tank intended to contain the washing or rinsing water, the bottom of which has a cavity with a substantially horizontal opening from which a drain pipe leads leading to a drain pump. Such a machine is for example shown in US Pat. No. 3,084,530. The cavity located at the lowest point of the tank acts as a sump allowing regular operation of the pump, without defusing, until the tank is effectively emptied.

Cette disposition, très commune, présente l'inconvénient de rassembler les corps solides dans la canalisation conduisant à la pompe. Ces corps solides sont d'une part les poudres de savon ou détergent entraînées dans l'eau de remplissage de la cuve, en début de lavage, et non complètement dissoutes lorsqu'elles atteignent le fond de cuve. Ces poudres, accumulées dans la cavité et la canalisation de vidange, ne seront pas brassées pendant le lavage, car elles sont éloignées des masses d'eau mises en mouvement par le tambour ou l'agitateur. Elles sont évacuées en début de vidange, constituant une perte qui peut atteindre 2091 de la poudre initialement disposée dans la machine par l'utilisateur.This arrangement, which is very common, has the drawback of collecting solid bodies in the pipe leading to the pump. These solid bodies are, on the one hand, the soap or detergent powders entrained in the filling water of the tank, at the start of washing, and not completely dissolved when they reach the bottom of the tank. These powders, accumulated in the cavity and the drain pipe, will not be brewed during washing, because they are distant from the bodies of water set in motion by the drum or the agitator. They are evacuated at the start of emptying, constituting a loss which can reach 2091 of the powder initially placed in the machine by the user.

Les corps solides sont d'autre part des objets étrangers, débris, épingles, boutons, pièces de monnaie... accidentellement introduits avec le linge à laver ou détachés de ce linge. Leur passage dans la pompe peut endommager cette dernière, l'obturer, ou obturer le filtre qui la protège.Solid bodies are on the other hand foreign objects, debris, pins, buttons, coins ... accidentally introduced with the laundry to be washed or detached from this laundry. Passage through the pump can damage the pump, block it, or block the filter that protects it.

L'invention a pour but de limiter la chute de ces corps solides dans la canalisation de vidange. Elle se caractérise par le fait que la canalisation de vidange ouvre sur le volume interne de la cuve par un orifice situé sur au moins une paroi latérale sensiblement verticale de la cavité, orifice en forme de fente horizontale localisée au-dessus du fond de la cavité.The invention aims to limit the fall of these solid bodies in the drain pipe. It is characterized by the fact that the drain pipe opens onto the internal volume of the tank through an orifice located on at least one substantially vertical side wall of the cavity, orifice in the form of a horizontal slot located above the bottom of the cavity .

La cavité se comporte alors comme un réceptacle dans lequel les corps solides se rassemblent sans être aspirés par la pompe de vidange. En particulier, si sa profondeur est faible, par exemple inférieure à ses dimensions horizontales, les poudre:, de savon ou détergent non dissoutes lors du remplissage pourront être brassées par la rotation du tambour ou de l'agitateur.The cavity then behaves like a receptacle in which the solid bodies collect without being sucked in by the drain pump. In particular, if its depth is small, for example less than its horizontal dimensions, the powder :, soap or detergent not dissolved during filling can be brewed by the rotation of the drum or the agitator.

La description qui suit et les dessins montrent un exemple de réalisation de l'invention.The following description and the drawings show an embodiment of the invention.

  • La figure 1 est une vue en perspective des deux parties désassemblées d'une cuve de machine à laver du type à tambour à axe horizontal.Figure 1 is a perspective view of the two disassembled parts of a washing machine tub of the drum type with horizontal axis.
  • La figure 2 est une coupe selon le plan vertical passant par l'axe de la cuve de la figure 1, les deux parties composant la cuve étant séparées.Figure 2 is a section along the vertical plane passing through the axis of the tank of Figure 1, the two parts of the tank being separated.
  • La figure 3 est une coupe semblable à celle de la figure 2, la cuve étant assemblée.Figure 3 is a section similar to that of Figure 2, the tank being assembled.

L'invention est ici appliquée à une machine à laver du type à tambour rotatif de lavage (non représenté) à axe horizontal et à chargement par le dessus. La cuve est, dans cet exemple, réalisée en matière thermoplastique injectée, telle que polypropylène allégé ou chargé de fibres. Elle comporte un corps formé en une seule pièce d'une virole 1 sensiblement cylindrique de révolution et d'un flasque 2 au centre duquel est situé un logement 3 pour un palier de tambour. Au sommet de la virole 1 débouche une trémie de chargement du linge 4. La cuve est fermée par un flasque 5 amovible formant couvercle, également percé d'un logement 6 pour palier de tambour. Les figures 1 et 2 montrent ces deux parties de la cuve séparées, la figure 3 les montre assemblées, mais ni les agrafes ou autres dispositifs de liaison, ni le joint inséré entre ces deux parties ne sont représentés.The invention is here applied to a washing machine of the rotary washing drum type (not shown) with horizontal axis and top loading. The tank is, in this example, made of injected thermoplastic material, such as lightened polypropylene or loaded with fibers. It comprises a body formed in one piece of a substantially cylindrical ferrule 1 of revolution and of a flange 2 in the center of which is a housing 3 for a drum bearing. At the top of the shell 1 opens a hopper for loading the linen 4. The tank is closed by a removable flange 5 forming a cover, also pierced with a housing 6 for drum bearing. Figures 1 and 2 show these two separate parts of the tank, Figure 3 shows them assembled, but neither the staples or other connecting devices, nor the joint inserted between these two parts are shown.

A la partie basse de son enceinte de révolution, la cuve présente, en contrebas de sa virole 1, une cavité ou premier puisard 7 de forme parallélépipèdique dans l'exemple dessiné. La cavité 7 est ouverte sur l'enceinte de la cuve. Dans l'exemple, deux parois verticales 8, 9, sont disposées longitudinalement par rapport à la virole, une troisième paroi 10 est transversale, quant à la quatrième paroi, également transversale, elle est constituée par un élément 11 appartenant au flasque amovible 5, qui vient s'adapter à la cavité 7 lorsque la cuve est assemblée (figure 3). Le fond de la cavité est sensiblement horizontal. La profondeur de la cavité est nettement inférieure à sa largeur, par exemple trois fois plus faible.At the lower part of its enclosure of revolution, the tank has, below its ferrule 1, a cavity or first sump 7 of parallelepiped shape in the example drawn. The cavity 7 is open on the enclosure of the tank. In the example, two vertical walls 8, 9 are arranged longitudinally by relative to the shell, a third wall 10 is transverse, as for the fourth wall, also transverse, it is constituted by an element 11 belonging to the removable flange 5, which comes to adapt to the cavity 7 when the tank is assembled (FIG. 3). The bottom of the cavity is substantially horizontal. The depth of the cavity is much less than its width, for example three times less.

La paroi verticale 8 est percée d'un orifice en forme de fente 12 horizontale située à distance du fond de la cavité. Cette fente 12 débouche dans un compartiment 13 n'ayant pas d'autre communication avec l'enceinte de la cuve et sensiblement parallèle à la cavité 7, situé également sous la surface cylindrique de la virole. Le compartiment 13 est ouvert sur une face et communique avec un second puisard 14 situé en contrebas et dont part, au point le plus bas, un conduit 15 destiné à être raccordé à la pompe de vidange. Le second puisard 14 est constitué d'un prolongement vers le bas de la cuve, constituant une sorte de double fond sur une partie de la longueur des génératrices de la virole 1. Il est limité par deux cloisons transversales constituées d'une part par le flasque amovible 5 et, d'autre part, par une cloison verticale 16 reliant la zone de double fond à la virole de révolution. Sur cette cloison 16 débouchent la cavité 7, le compartiment 13 et le conduit 15. Lorsque la cuve est assemblée, le second puisard 14 ne communique avec l'enceinte de la cuve que par le compartiment 13, la fente 12 et la cavité ou premier puisard 7. Entre ces volumes successifs, l'étanchéité n'a pas à être rigoureuse car, lorsque la cuve est pleine d'eau, il sont tous submergés.The vertical wall 8 is pierced with a horizontal slot-shaped orifice 12 located at a distance from the bottom of the cavity. This slot 12 opens into a compartment 13 having no other communication with the enclosure of the tank and substantially parallel to the cavity 7, also located under the cylindrical surface of the shell. The compartment 13 is open on one side and communicates with a second sump 14 located below and from which leaves, at the lowest point, a conduit 15 intended to be connected to the drain pump. The second sump 14 is constituted by a downward extension of the tank, constituting a sort of double bottom over part of the length of the generatrices of the shell 1. It is limited by two transverse partitions formed on the one hand by the removable flange 5 and, on the other hand, by a vertical partition 16 connecting the double bottom zone to the ferrule of revolution. On this partition 16 open the cavity 7, the compartment 13 and the conduit 15. When the tank is assembled, the second sump 14 communicates with the enclosure of the tank only through the compartment 13, the slot 12 and the cavity or first sump 7. Between these successive volumes, the seal does not have to be rigorous because, when the tank is full of water, they are all submerged.

La succession de ces volumes 7, 13, 14, est destinée à imposer un trajet de vidange à l'eau. Ce trajet est désigné sur les figures par les flèches T. Le fait que l'orifice en forme de fente 12 ne soit pas au fond de la cavité 7 évite que les corps solides tombés au fond de cette cavité soient entraînés lors de la vidange de la cuve. La forme de fente de l'orifice 12 contribue également à faire obstacle à l'aspiration de ces corps solides.The succession of these volumes 7, 13, 14 is intended to impose a drain path on the water. This path is designated in the figures by the arrows T. The fact that the slot-shaped orifice 12 is not at the bottom of the cavity 7 prevents the solid bodies fallen at the bottom of this cavity from being entrained during the emptying of tank. The slit shape of the orifice 12 also contributes to obstructing the suction of these solid bodies.

Par sa faible profondeur, la cavité 7 est facilement accessible, de l'intérieur de la cuve. Par exemple, l'utilisateur y accède de la main par la trémie 4, après ouverture de la porte de chargement du tambour de lavage et d'une trappe diamétralement opposée dans la virole du tambour. Il est ainsi possible d'inspecter périodiquement, sans démontage de la cuve, la cavité 7 pour en retirer les objets solides.By its shallow depth, the cavity 7 is easily accessible from inside the tank. For example, the user accesses it by hand through the hopper 4, after opening the loading door of the washing drum and a diametrically opposite hatch in the shell of the drum. It is thus possible to periodically inspect, without dismantling the tank, the cavity 7 in order to remove the solid objects therefrom.
